All North Shore beaches on Kauai, from the Hanalei Pavilion to Kee Beach, have been closed to swimming Wednesday due to high surf conditions. Ocean Safety officials report wave heights of up to 20 feet in these areas.

Swimmers are advised to swim at guarded beaches in Poipu and Salt Pond instead.

Lifeguards will remain at the beach towers throughout the day to notify beachgoers of the closure. All beaches will reopen as officials deem them safe for swimming.

The National Weather Service has posted a high surf warning along all north- and west-facing shores of Kauai, Niihau, Oahu and Molokai and north-facing shores of Maui until 6 p.m. Wednesday. The warning may be extended or modified as conditions develop.
